Abstract
The invention discloses a non-destructive removing method of a temporary support in continuous beam construction. A non-destructive removing structure comprises a temporary support, a jack, an upper wedge, a middle wedge and a lower wedge. The upper wedge, the middle wedge and the lower wedge are sequentially stacked between the temporary support and a continuous beam. A notch with an opening facing outwardly is formed between the upper wedge and the lower wedge. The middle wedge is inserted into the notch. An L-shaped steel plate which extends outwardly and bends downwardly is embedded in the middle wedge to form a counter-force seat. When the temporary support needs to be removed, the jack is mounted between the L-shaped steel plate and the temporary support, and the temporary support can be disconnected from the continuous beam by hoisting the jack. By the non-destructive removing method, the temporary support can be used repeatedly, social resource waste is reduced, no environmental pollution is caused, fast mounting and removing of the temporary support are achieved, construction efficiency is improved, industrialization of temporary supports is achieved, and average construction cost is lowered greatly.
Description
?
Technical field
The present invention relates generally to the construction of continuous beam utilization temporary support, relates in particular to a kind of harmless method for dismounting of temporary support that is applied in the Construction of continuous beam.
?
Background technology
In Construction of continuous beam, temporary support often adopts concrete or steel reinforced concrete integrated structure form, uses mechanical breaking in the demolishing process or adopts the mode of acetylene cutting to remove, and demolishing process is that violence is removed, and temporary support is damaged, and can not have enough to meet the need use.At present, mainly there is following problem in traditional temporary support method for designing:
1, temporary support is disposable input, can not have enough to meet the need use, causes the social resources waste, and pollutes local environment.
2, temporary support adopts concrete structure, takes a lot of work during construction cost.
3, temporary support adopts concrete structure, must abolish after construction finishes, and increases construction cost indirectly.
Summary of the invention
The present invention seeks to for fear of above-mentioned existing in prior technology deficiency, a kind of harmless method for dismounting of temporary support that is applied in the Construction of continuous beam is provided, so that temporary support can have enough to meet the need use, convenient and quick construction has reduced construction cost simultaneously.
The present invention realizes through following technical scheme:
A kind of temporary support can't harm dismounting structure, includes temporary support, jack and upper, middle and lower wedge, it is characterized in that: temporary support adopts the shaped steel assembly welding to form, and can have enough to meet the need use.Be stacked with the upper, middle and lower wedge between said temporary support and the continuous beam successively, be formed with a breach that opening is outside between the said upper and lower wedge, said middle wedge inserts in the breach.Said upper, middle and lower wedge is a concrete structure, and the said soffit of wedge, the upper surface of following wedge and the upper and lower surface of middle wedge of going up is respectively equipped with steel plate, reduces the frictional force between the voussoir with this.
The L shaped steel plate that is embedded with protruding and downward bending in said in the wedge forms the counter-force seat, and the bending end of said L shaped steel plate is welded with the triangle stiffened panel, strengthens the non-deformability of L shaped steel plate with this.
When carrying out temporary support when removing, between the bending end of L shaped steel plate and temporary support sidewall, add jack.Through the jacking jack, wedge separates with upper and lower wedge in making, thereby makes on the bearing of continuous beam whereabouts, and separates with temporary support.
Advantage of the present invention is:
1, temporary support can reuse among the present invention, reduces the social resources waste, and does not pollute local environment;
2, the present invention has realized temporary support quick-assembling and dismounting, improves efficiency of construction;
3. the present invention has realized the temporary support commercialization, reduces the input of average construction cost greatly.

The specific embodiment
To shown in Figure 3, a kind of temporary support can't harm dismounting structure, includes temporary support 2, jack 9 and upper, middle and lower wedge 4,5,6, it is characterized in that like Fig. 1: temporary support 2 adopts the shaped steel assembly welding to form, and is directly installed on the pier shaft 1.Be stacked with upper, middle and lower wedge 4,5,6 between said temporary support 2 and the continuous beam 3 successively, said upper and lower wedge 4, be formed with a breach 7 that opening is outside between 6, said in wedge 5 insert in the breach 7.Said upper, middle and lower wedge 4,5,6 is a concrete structure, and the said soffit of wedge 4, the upper surface of following wedge 6 and the upper and lower surface of middle wedge 5 of going up is respectively equipped with steel plate 10, to reduce the frictional force between the voussoir, the separation between being convenient to.The L shaped steel plate 8 that is embedded with protruding and downward bending in said in the wedge 5 forms the counter-force seat, and the bending end of said L shaped steel plate 8 is welded with triangle stiffened panel 11.When carrying out temporary support 2 when removing, between the bending end of L shaped steel plate 8 and temporary support 2 sidewalls, add jack 9.Through jacking jack 9, wedge 5 separates with upper and lower wedge 4,6 in making, thereby continuous beam 3 is separated with temporary support 2.
Claims (3)
